heads up seven card stud

[steveyboy]

I am playing in a heads up tourney in a couple of weeks time. As part of this I must play heads up limit seven card stud. As I have never played the game before I wondered if anyone could point me in the right direction as regards books/computer programs and general advice.
I have read the super systems chapter on seven card stud but think this doesn't really cover heads up play.

Looking forward to your help.
